: Can someone help me to write a program to calculate the value of x for which f(x) = 0 zero for the general quadratic equation. Use the quadratic formula.: : a.The program should have input boxes for a, b and c where a, b, and c are the coefficients of x2, x1 and x0: : b.And out put the solutions for x.: : c.if the solution contains the square root of a negative number then the program should print the message this equation has complex roots and out put the complex roots.: : : plz i'm really in need of help: : Place a couple of TLabels, TEdits and one TButton on the form. In the TButton.OnClick event code the following:Use the StrToFloat() to convert the TEdit.Text property to doubles. This will give you the a, b, c coefficients as numbers, so you can calculate with them.Then comes the maths part, just like you would do on paper. You might need an if-then-else-if-then-else statement to check the various answer possibilities:[code] if D < 0 then begin // Do something end else if D = 0 then begin // Do something else end else { no need for another if-then, because if the program gets this far, D is not smaller or equal to 0, thus greater than 0 } begin // Third do something end;[/code]Finally use FloatToStr() to convert the results back to strings to show them using another few TLabels.
